What is Domain Authority?
Domain Authority (DA) is a third-party SEO metric developed by Moz (scored 1–100) that predicts how likely a domain is to rank in search results based on its backlink profile and overall web authority. Reddit.com has a Domain Authority of approximately 91, placing it among the highest-authority domains on the internet alongside Wikipedia, YouTube, and Amazon. This means Reddit pages — including individual post and comment threads — rank in Google for competitive keywords with much less effort than equivalent content on a lower-DA domain. A Reddit post can rank for a keyword that would require months of backlink building on a new domain.
Why it matters for Reddit marketing
Reddit's domain authority is the SEO foundation of the 'Reddit as organic search channel' strategy. Posting content on Reddit leverages decades of Reddit's accumulated backlink authority, meaning your post inherits the domain's ranking power. For early-stage SaaS companies with new, low-DA websites, creating content on Reddit for product-related search terms is often more effective than trying to rank the company blog for the same terms.
